Pilonidal Sinus

A pilonidal sinus is a small infected cavity or tunnel that develops in the skin, usually near the tailbone at the top of the buttocks. It commonly affects young adults and people who sit for long hours. While it may begin as mild discomfort or swelling, a pilonidal sinus can quickly become painful, recurrent, and infected if left untreated.

Early diagnosis and proper treatment are essential to prevent repeated infections and complications.

What Is a Pilonidal Sinus?

A pilonidal sinus is an abnormal tract under the skin that often contains hair, debris, and infected tissue. It can form a cyst or abscess and may develop one or more openings on the skin that discharge pus or blood.

The condition tends to recur if not treated properly.

Common Causes of Pilonidal Sinus

Pilonidal sinus usually develops due to:

• Ingrown hair in the natal cleft

• Prolonged sitting or sedentary lifestyle

• Excess body hair and sweating

• Friction and repeated local trauma

• Poor local hygiene

Hair and debris get trapped under the skin, leading to infection and sinus formation.

Symptoms of Pilonidal Sinus

Common symptoms include:

• Pain or tenderness near the tailbone

• Swelling or redness between the buttocks

• Pus or blood discharge from a small opening

• Foul-smelling drainage

• Difficulty sitting or walking comfortably

Symptoms may temporarily settle but often recur without definitive treatment.

Why Delaying Treatment Makes It Worse

Many patients ignore early symptoms or rely on antibiotics alone. Delaying treatment can lead to:

• Repeated abscess formation

• Multiple sinus tracts

• Chronic infection and scarring

• Longer recovery time and higher recurrence rates

Early-stage disease is simpler to treat with better outcomes.

How a Proctologist Treats Pilonidal Sinus

Treatment depends on the stage and severity and may include:

• Drainage of abscess if infection is present

• Definitive procedures to remove the sinus tract

• Minimally invasive techniques to reduce pain and downtime

• Guidance on hygiene, hair control, and prevention of recurrence

Proper treatment aims at complete removal of the disease and long-term relief.

When Should You See a Proctologist?

Consult a specialist if you notice:

• Recurrent pain or swelling near the tailbone

• Persistent or recurring discharge

• Difficulty sitting due to discomfort

• Repeated infections despite medication

Early consultation helps prevent complications and repeated procedures.

Key Takeaway

A pilonidal sinus is a chronic and recurrent condition that rarely heals on its own. Ignoring symptoms or delaying treatment often leads to repeated infections and prolonged discomfort.

If you suspect a pilonidal sinus, early evaluation by a qualified proctologist ensures effective treatment, faster recovery, and reduced chances of recurrence.
